Pay per token. Runs inside AWS and GCP, in your region. One API call, nothing to deploy.
Full-speed Celeris-1. Pay for what you use.
Typed decisions with probabilities. Pay for what you use.
For teams running Celeris on the critical path at scale.
Prices in USD. Billed per million tokens; input and output metered separately. Celeris-1 Decision output tokens are free, explanations included.
Celeris-1 is the first model from Celeris: a general purpose language model that delivers near-GPT-5 level intelligence with up to 15x faster response times. It scores 75.9% on MMLU-Pro at a p50 latency of 158ms, and up to 81.4% with reasoning enabled.
Celeris-1 is built from the ground up for low latency rather than adapted for it after the fact. We measure intelligence and speed on the same footing and publish the methodology, so you can verify the tradeoff yourself: 75.9% on MMLU-Pro at a p50 latency of 158ms with reasoning off, or up to 81.4% with reasoning enabled when latency matters less.
Yes, and we publish everything. One harness, identical prompts and scoring across GPT-5, GPT-5-mini, Gemini 2.5 Flash, and Celeris-1. Every claim on this site links back to that data.
Voice, agents, and real-time applications. Anywhere waiting for a model breaks the experience, Celeris-1 is built to remove the wait.
Yes. Every plan runs the same full-speed Celeris-1: same weights, same latency, same quality. Speed is the product, not a premium tier, so what you test is exactly what you ship.
Per million tokens, input and output metered separately. No reserved capacity, no idle GPU charges, no surprises at the end of the month.
A model built for decisions rather than text. You send text, structured data or images and the questions you want answered; it returns a probability for each answer, and a one-sentence explanation if you ask for one. Same request format as other decision models. See Celeris-1 Decision.
$0.04 per million input tokens. Output tokens are free, including explanations. Images count as input tokens, and you control how many with the resolution setting on each request.
Celeris-1 when you need generated text: chat, agents, voice, anything that writes. Celeris-1 Decision when you need a yes or no, a choice or a score that your code acts on directly. Many teams run both: the decision model routes, the language model responds.
Enterprise plans can deploy in your VPC, in your region, so requests never leave your cloud's network. Talk to us about compliance and data residency requirements.
